Application filed October 27, 1927. Serial No. 229,092.

The invention relates to improvements in mechanical devices which areintended to maintain a natural and plentiful supply of oxygen to theblood of human beings durlng the sleeping hours; and the objects of theimprovement are, first, to provide a clear and unobstructive outlet orchannel for the more rapid exhalation of impure air from the lungs ladenwith carbon dioxide gas, having performed its function in oxidation ofthe blood and to provide an uninterrupted passage of fresh air with itsnormal content of oxygen to said lungs;second, to afford facilities forthe proper inhalation of oxygen laden fresh air and the properexhalation of impure or carbon dioxide laden air.

One form of the invention is illustrated in the accompanying drawing inwhich Figure 1 is a vertical sectional view, showing the device in use;

Fig. 2 is a perspective view looking at the front of the device;

Fig. 3 is a perspective View of the rear of the device.

Referring now to the drawings, the device comprises a front plate member1 having a curvature corresponding to the arc of curvature of the upperand lower front teeth. The plate member cooperates with a body portion 2to form an upper interior channel 3 to receive the upper front teeth ofthe user, and to foi m a corresponding lower interior channel 4 toreceive the loWer front teeth. These two channels are spaced apart, sothat when in place the upper and lower front teeth will be held apart,apoint which is of -importance because it props the teeth apart so thatair may pass in and outfreely, and it moves the jawbone downward, whichmoves the epiglottisand uvula at the back of the mouth so as to providea clearer and larger passage of air to and from the throat andlungs.

The respirator is provided with a central air passage 5 which opens intoboth the upper and lower grooves 3 and 4, so-that part of the exhaledair, for example, passes over the body portion 2 and down and out ofpassage 5, and another part passes under the body portion 2 and up andout of passe 05.

e top of the body portion 2 is provided with two knobs or projectionsGdefining between them an air channel 7. The projeca tions 6 support thetongue above and away from the air passages 5 and 7 and so prevent thetongue from closin the air passages even While the user is asfiaep. Q

When the teeth from dental work or from any other reason come too closetogether or perhaps shut entirely all the soft musclesof the throatsupporting the epiglottis (8) and the uvula and draw down together thusreducing the space afforded by the mouth for the exhalation of theimpure. air coming from the lungs which is laden with carbon-dioxide.

I he inhalation of fresh air and the exhalation of impure air is thusinterfered with,

with resultant discomfort to the sleeper, resulting sometimes inunpleasant noises. With this invention, the teeth are propped apart,which moves the epiglottis and uvula so as to enlarge the air passagesand at the same time there is provided at all times a clear inlet andoutlet passage for the air through the respirator between the teeth.

The respirator may be made of hard or soft rubber, or other suitablematerial.
